Overview
ETE NIOAQUE is a secondary wastewater treatment plant serving 2,110 people in Nioaque, Mato Grosso do Sul, Brazil. It discharges 496.80 cubic meters of treated effluent, supporting local water quality in the Paraguay River basin.
ETE NIOAQUE is a municipal wastewater treatment plant located in Nioaque, a town in the state of Mato Grosso do Sul, Brazil. The plant serves a population of approximately 2,110 residents, making it a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazil's national environmental regulations (CONAMA resolutions and the National Water Resources Policy), secondary treatment is typically required for urban wastewater to protect receiving water bodies. The plant discharges an average of 496.80 cubic meters of treated wastewater daily. The treated effluent from ETE NIOAQUE is released into local waterways that drain into the Paraguay River basin, a major hydrological system in South America. This basin supports diverse aquatic ecosystems and is part of the larger Paraná-Paraguay river system, which flows into the Río de la Plata estuary. Proper treatment helps maintain water quality for downstream communities and wildlife.
Environmental context
The plant's discharge enters the Paraguay River basin, which flows through the Pantanal, one of the world's largest tropical wetlands. This ecologically sensitive region supports a rich diversity of fish, birds, and aquatic plants. The Paraguay River ultimately joins the Paraná River to form the Río de la Plata estuary, making upstream treatment crucial for downstream ecosystem health.
